    Abstract: A microwave control method is used in a microwave plasma processing apparatus including a microwave generation unit, a waveguide for guiding a microwave generated by the microwave generation unit, a tuner for controlling a position of a movable short-circuiting plate, and a stub provided between the tuner and an antenna in the waveguide and insertable into an inner space of the waveguide. The method includes detecting the position of the movable short-circuiting plate controlled by the tuner for the microwave outputted by the microwave generation unit, determining whether or not a difference between a reference position and the detected position of the movable short-circuiting plate is within a tolerable range, and controlling an insertion length of the stub into the inner space of the waveguide when it is determined that the difference between the position of the movable short-circuiting plate and the reference position is not within the tolerable range.

    Abstract: A dielectric window for a plasma treatment device for a plasma treatment device that uses microwaves as a plasma source. The dielectric window is circular-plate-shaped and allows microwaves to propagate. The dielectric window has a recess that has an opening on the lower-surface side and that indents in the plate thickness direction of the dielectric window, and is provided to the lower surface at which plasma is generated when the dielectric window is provided to the plasma treatment device. The recess has a bottom surface extending in the direction perpendicular to the plate thickness direction, and a side surface extending in the plate thickness direction from the circumferential edge of the bottom surface toward the opening of the recess. In addition, an inclined surface extends at an incline relative to the plate thickness direction from the opening-side circumferential edge of the side surface toward the opening of the recess.

    Abstract: A plasma processing apparatus includes a processing container that defines a processing space, a gas supply unit provided on a sidewall of the processing container and configured to supply gas to the processing space, a dielectric member having a facing surface that faces the processing space, and an antenna provided on a surface opposite to the facing surface of the dielectric member and configured to radiate microwaves that turn the gas into plasma to the processing space through the dielectric member. The gas supply unit includes a transport hole transporting the gas to a position where the gas does not reach the processing space in the inside of the sidewall of the processing container and an injection hole communicated to the transport hole and configured to inject the gas transported to the position into the processing space. The injection hole has a diameter larger than that of the transport hole.
